VALVE MECHNIM FOR INI'ERNAL-COMBUSTION MOTORS,

Application aied Apri124, 1912.

To 077 whom t omg/concern:

Be it known that I, Aimar R. HENDRIX, a citizen of the United States, residing at Chi cago, in the county of Cook and State of Illinois,v have invented certain new and useful Improvements in. Valve Mechanism for Internal-Combustion Motors' and the like, of which the following is a description.

My invention relates to the mechanism for controlling the entrance of fluid to, and its escape from the comblistion chamber or cylinder of the motor.

The object of my invention is to provide a simple, convenient, durable and extremely accurate and reliable device of the kind described in which the moving parts are comparatively free from the influence of high temperature which might interfere with the operation of the device and is liable to cause distortion orv deterioration of the parts.

To' this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described' and more particularly pointed out in the In the accompanying drawings wherein like or similar reference characters indicate like or coi-responding parts: Figure 1 is a transverse section taken substantially on line 1-l of Fig. 2. Fig. Q is a longitudinal section taken substantially on line 2 2 of' Fig. 1. Fig. 3 is a sectional detail of the movable member and associated parts taken substantially on line 3&3 of Fig. 2. Fig. 4,

is a view similar to Fig. 2 but showing a slightly modified form of my device.-

In the form of my device shown in the drawings 1 is the rear end of the cylinder or combustion chamber of an internal. combustion engine having a head or cover 2 upon which my improved valve mechanism is mounted in any convenient manner. As shown a cylindrical casing 3 is formed upon the head 2 and provided with an inlet opening 4 and an outlet opening 5 through which the combustible is introduced to the cylinder and the spent gases are discharged. In the form shown the `openings 4 and 5 are substantially opposite each other and con- 5o nected to suitable pipes or tubes 6 and 7 for directing the fuel to', and the vspent gases from, the device. A port 8 is provided in the casing substantially midway between the openings 4 and 5 and extends from the casing 3 to the interior of the cylinder. The

' slot or opening 10 ormed in the wall of the member will successively register with the openings and the `port. The size and form of the slot is so proportioned that communication cannever be opened directly between the openings 4 and 5, thatvis, the member 9 is so formed that one will always be closed before the other is opened; but a direct passage through the casing may be opened between the openings 4 or 5 as desired and the. port 8. The several parts are .so proportioned that when the memberQ-'is rotated in the direction indicated inthe drawings the outlet opening 5 is first connected to the port 8 after which the opening 5 is closed and almost immediately the inlet opening 4 is connected to the port. The continued movement of the member 9 closes the port 8 when the member has completed approximately one-half of a rotation, and during the remainder ofthe rotation theopenings 4 and 5 and port 8-remain closed; the periods of course' accurately corresponding to the operating events of the motor.

In the preferred construction a recess 11 is formed `in the casing 3 directly opposite the port 8 and extends longitudinally of the casing. An adjustable bearing block 12 is positioned in the recess With suitable screws 14 or other convenient means for adjusting the bearing block tothe member 9 so as to holdthe member firmly upon its seat and in sure a suitable joint between the member and casing adjacent the port, and prevent the escape of any gases during the power stroke of the moto In the preferred form shown the casing 3 and member 9 are substantially the same length and a pair of plates or fianges 15 and 16 are attached to the ends of the casing with their central portion projecting inward beyond the Walls of the member 9 thereby preventing longitudinal movement of the member in the casing but without interfering with the free circulation of air through the member which is preferably made tubular to avoid excessive heat and roo consequent distortion. Any suitable means may be provided'for rotating the member 9. In theform shown a bearing 1T is provided upon the flangeljadapted to "support a 5 shaft 18 concentric with the member 9; a .driver 19 is provided upon the shaft arranged to extend .into a pair of notches or recesses 20-'&20y near the extremity of the member 9- so that when the shaft 1S is ro- A10A tated the driver 19 will engage the walls` of the notches 20 and irotate the member. ln V the preferred construction to avoid iniproperly engaging the driver lil with the vnotches 20 I extend the shaft 1S into the. member 9 sufhciently to insure the end of the shaft extending beyond'the wall of the slot 10 or other convenient portion upon the interior of the iiieiiibei'. The end of the shaft is cut awa v as at Je() oi otherwise so formed that it will engage the part of the member J and prevent the engagement of the driver 15) with the slots 2() except when thef'parts are in the proper relation to each other.

In the form shown in Fig. l `a pair of closures 25 are provided at the "respective ends of the member 9 havingl projecting r hubs 2T and :Z8 respectively lach adapted to receive.l a hollow shaft or tube. :Z9 and 30. r1`he lianges 32 and iii/cach operate as before described to prev uit longitudinal movement of the member in the casing. In this forni suitable means may be provided for directing a stream of water or other cooling medium through the shaft l0 into the. interior of the member 9 whence it will escape through the shaft 30 thus cooling the niember and controlling the temperature of the memberas desired.

Having thus described my improvement v fit' is obvious that various immaterial modifi- `cations may he made in my device without departing from the spirit of my invention, hence l do not wish to beunderstood as limitingmyself to the exact formlor construction shown. L:
